My computer's ip is 192.168.2.20, and my tablets is 192.168.2.2 - does that mean they are on the same subnet? (I'm a complete beginner...)

I tried checking the log files on my computer for CopSSH, but they seemed empty (specifically the "sshd-stderr.log" and "sshd-stdout.log" files) - what do you mean by "your login shell is b0rked."?
